Control relays overview

MonitorControl relays are

measurement units that

continuously monitor

electrical values within

established parameters.

ControlOutput relays operate

with positive logic,

contacts are closed on

normal conditions and

will open when control

electronics detect

network faults.

ProtectionYour equipment is

protected against

network faults and all

associated damages.

SignallingOperating set, working

status and failure

conditions are informed

through rotary selectors

and signalling led

located on the front

face.

Aimed to protect motors where phase sequence is specially relevant (lifts, cranes, escalators,..) or phase failure can be specially damaging.

RC RTM

Industrial process requiring additional protection and preventive action install complex voltage monitoring relays that additional to phase failure and sequence protection offer voltage control within established threshold and adjustable timings. We find it in automation systems, refrigeration, network transfers.

Managing water and conductive liquids are an essential part of modern societies illustrated in water plants, factory production processes, agriculture irrigation, pools,.. Pumps are the core of liquid flow systems and they require efficient control in order to avoid service continuity problems and expensive costs associated to system breakdowns such as pump dry running.

Reinforced electronics

Pump control relays

ApplicationsPumping systems• Water plants• Sewage plants• Irrigation• Industrial liquid systems• Pools•

MonitorLevel controllers can

adjust sensitivity

measurement to specific

liquid conditions and

monitor filling/draining

on wells and tanks.

Double types offer

optimum coordination

between two different

reservoirs.

SafetyTransformer insulation

between measuring

circuit and command

circuit guarantees safety.

ProtectionYour equipment is

protected against idle

functioning and live is

enlarged by balancing

loads. Varistor

protection on the

electronic circuit

prevents damages on

the control due to

lightning effects.

SignallingSensitivity adjusment,

Conductive liquids are monitored by level control relays that operate based on the principle of liquid resistivity. Sensitivity adjustment permits adapting the circuit to each specific liquid characteristics. Control relays prove more reliable than float switches which demonstrate faulty with vibration, condensation, or polluted environments.Level controllers will command the pump on filling and draining operations.

Compact surge protector devices (SPD) are developed to meet overvoltage protection needs for low voltage networks. These overvoltages are mainly generated by lightning although also industrial changeovers and network failures. They provide common/differential protection.

The electrical scheme on PST are based on high energy varistors equipped with thermal disconnector and associated to specific gas discharge tubes GDT.

According to standards • IEC 61643-1 • EN 61643-11

protectorClass III




The AC power surge protectors are split into 3 categories by IEC 61643-1 and EN 61643-11 standards, with the following 3 classes of tests. These different tests depend on the location of the surge protector in the AC network and on the external conditions.

Type of surge protectors

Surge protectors parameters

Uc Operating voltageIs the maximum r.m.s voltage which may be applied continuously to the SPD.

Imax Discharge current

Applicable to Type 2 SPD, is the maximum impulse current 8/20 μs a surge protector can withstand without destruction .

In Nominal discharge current

Is the level of impulse current a surge protector Type 1 or Type 2 can withstand repeatedly (15 surges) without destruction.

Iimp Impulse currentUsed in Class I test applicable to Type 1 SPDs, is the maximum impulse 10/350 μs current a surge protector can withstand without destruction. This test simulates the effect, on AC power surge protectors, of a direct lightning strike on an installation.

Up Protection levelThis is the maximum voltage on the surge protector output when subjected to an impulse current equivalent to its nominal discharge current (In). This parameter characterizes the performance of the SPD in limiting the transient overvoltage to protect the equipment.

Type 1 surge protectors are designed to be installed where a direct lightning strike risk is high, especially when the building is equipped with external lightning protection system (LPS or lightning rod). In this situation, EN 61643-11 and IEC 61643-1 standards require the Class I test to be applied to surge protectors : this test is characterized by the injection of 10/350 μs impulse current in order to simulate the direct lightning strike effects. Therefore these Type 1 surge protectors must be exceptionally powerful to conduct this high energy impulse current.

ClassIType 2 surge protectors are designed to be installed at the beginning of the installation, in the main switchboard, or close to sensitive terminals, on installations without LPS (lightning rods). These protectors are tested following the Class II test from IEC61643-11 or EN61643-11standards and based on 8/20 μs impulse current injection.

IIClass

In case of very sensitive or remote equipment, secondary stage of surge protectors is required : these low energy SPDs could be Type 2 or Type 3.Type 3 SPDs are tested with a combination waveform (1,2/50 μs - 8/20 μs) following Class III test.

Protector Advanced Technology

Operating principle

PST surge protectors are based on zinc metal-oxide varistors (MOV), the best compromise between a fast response time (<25 ns) and a high discharge current capacity, which are the main parameters to provide effi cient protection.Surge protection is highly improved by combining varistors with a specifi c gas discharge tubes (GDT).

Improved performance is specifi cally attested in;

protection level (Up)• life duration (due to the • supression of leakage current)continuous operation and • power quality (no follow current)

V : VaristorFt : Thermal fuset˚ : Thermal disconnectionC : Remote signaling contact

Nevertheless the end of life of these varistors must be absolutely monitored thus requiring the systematic use of built-in thermal disconnection devices.

Disconnection devices

Internal thermal ▪ security which will disconnect the surge protector from the AC network in case of thermal runaway. In such a case, the user will be warned about the trouble by an indicator (mechanical or light) in front of the protector and will carry out the replacement of the defective SPD.

External electrical • disconnection (fuses or breaker) to disconnect the surge protector from the AC network in case of internal short circuit, e.g. due to an excessive impulse current.

In compliance with the standards, the AC power surge protectors are equipped with external and internal disconnection devices in order to provide total safety in case of failure.2 types of disconnection devices are necessary:

The rating of the external fuses (or breaker) are in relation with the discharge capability of the SPD and the prospective short-circuit current of the installation.

Lightning surges occur essentially between active conductors and earth. A live conductor not only refers to the phase conductors but also to the neutral conductor. These overvoltages are protected on Common mode.

Diff erential overvoltages can occur between live conductors when we are operating on a TT earthing system. It can also appear on TN-S eartingh systems if there is a signifi cant length diff erence between PE and N

cables. The standard IEC 60364 allows combination of protection between phases and neutral (diff erential mode) and between neutral and ground (common mode) this type of mounting is named “CT2 connection” .

Coordination of Surge Protectors

In order to provide maximum protection effi ciency, it is necessary to create a «coordination» diagram, that means installation of a «primary» SPD at the network entrance and a «secondary» close to sensitive equipment.

This association is required in the 2 following cases :

High sensitivity equipment : • Voltage protection level upstream is too high with regards to withstand level capability of protected equipment.

Long distance (greater than 30 • m) of wire between equipment to be protected and primary SPD : Reduction of ringing voltages created during the surge transmission.

Effi cient SPD coordination is performed by including between primary and secondary SPDs a minimum length of wire (> 10 m).

Installation rules

Surge protectors are connected in parallel on the AC network and must be equipped with external fuses for short-circuit protection.

Total length of connection wires to AC network must be lower than 0,5m in order to mantain protection level as the impedance of these connections reduces the protection provided.

Protection wire coming from SPD must be connected to bonding bar. Paralleling protection wire with phases conductors must be avoided.

Type 2 protectors require wires with 4mm2 minimum cross-section. Type 1 require minimum 10mm2.

Class I

The PST4B100 is a compact Class I Surge Protector Device designed to be connected at the entrance of the electrical installation on 3-Phase networks. This device provides effi cient protection against direct and indirect eff ects of lightning phenomena on electrical networks. This protection is specially adequate on those buildings endowed with lightning rods or LPS systems.

This protection is based on

combining high discharge capacity MOV varistors with specifi c GDT providing common and diff erential mode protection. This technology allows the best performance with no follow current neither leakage current, while achieving an elevated (Up) level of protection.

This SPD is draws attention for its extremely modular compact size, easy to install on DIN rail, and individual visual indicator on each phase.

Surge protectors for telecom and data lines

Class III surge protectors are designed to protect, against surge voltages telecom lines, data lines, and automation PLCs and industrial buses. These elements are characterised for their high sensitiveness and the elevated cost that any overvoltages can cause on the equipment to be protected.

DLA protections combine gas discharger tubes and fast clamping diodes in order to provide high discharge current capability and fast operation. These protections are installed on symmetrical DIN rails and are equipped with removable modules for easy maintenance (line continuity in case of plug-in module removal).

Three phase installation

Protection against permanente or temporary overvoltages (TOV) require disconnecting the equipments from the installation. We can not shunt temporary to ground as we are dealing with large time scale overvoltages.

Temporary overvoltages are typically due to neutral fault in the network and specially required on those installations with unstable networks showing regular fluctuations and power cuts.

Our range of RF02 is specially suitable on 3Ph (or 3Ph+N) supplies and its operating conditions. You can consult on Control Relays catalogue or use PSP on 3Ph installation when actuating on RCD and/or manual reset/test characteristics is required.

! Wrong connection

Neutral wrong connection. Does not distinguish connection between L1,L2 and L3. This condition during an extended period will damage the device. Remake connection.

Permanent

Overvoltage

Permanent overvoltage on phases blinking. Relay and auxiliary contact closed..

Protector PSP-3 does actuate by the means of the output relay on the shunt trip coil of the breaking element (MCB or MCCB). Permanent overvoltage protector distinguishes on integrating a voltage free auxiliary contact for external signalling. The protector does also operate on test mode.

Signalling




Combining protections

Industrial, IT and services facilities face increasing demand on transient and temporary overvoltage protections in order to secure valuable equipments. Installation normative updates are improving equipment protection by writing down new requirements. Gave offers a complete range of combined solutions that warrant flexible installation and easy maintenance.

FlexibilityThe protector is installed upon space availability on the panel. Easy to place transient protection close to the earth connection.

Single phase installation Three phase installation

Remote signallingProtectors are equipped with remote signalling. We can distinguish if we have transient or temporary/permanent overvoltage condition.

MaintenanceFriendly maintenance. When a transient varistor protection ends its live we only need to replace this phase cartridge remaining other modules operative.
